pub const LOCK_CONFIG_MAGIC: [u8; 4];Expand description
Magic word for CommandOpcode::LockConfigZone. Picked to be a
distinctive 32-bit value (DE AD BE EF).
Exposed pub so the host CLI in tools/hsm-host can build the same
payload byte sequence without re-declaring the constant. The crate is
the single source of truth for the wire format; the CLI is a consumer.
